LUBRICATING SYSTEM FOR AUTOMOBILES AND OTHER MOTOR CARS.

Application filed May 4,

. My present. invention relates ge'nerallv to lubricating systems for automobiles and other motor cars having a plurality of points tobe luln'icat'ed and is more particularly a central feeds vstem embodying certain improvements over that system doscribcd and claimed in my co-pcuding application No. 19,933, which was tiled April 1, 19:25.

I An'iong the various objects and advanat present. my invention aims to provide means for lul'iricating springs. spring shackle bolts, steering gears, steering knuckle bolts. clutch throw-out collars, and various oth r points from a central reservoir having means whereby to prevent the exhaustion of its lubricant, and in this way prevent the entrance of air into the ced pipe leading from the reservoir and the various branches of this pipe extending to the several. points to be lubricated.

A still further object is to provide a systein including a reservoir and a feed pipe. leading from the reservoir having branch pipes extending to various points to be lubricated, and also including means at the various points to be lubricated for controlling the feed of lubricant to these points. the said feed control means being of such nature as to permit of the formation ot a partial vacuum in the feed pipe and its branches in conjunction with a valve in the feed pipe whereby the latter may he cut off, and 'a still further object. is the provision of such an arrangen'ient wherein the Said valve of the feed pipe is also adapted for use as a drip valve without destroying the function of the feed control means.

In the accom 'ianyiug drawings which present invention and form a part of this specification: 7,

pending axial 1925. Serial No. 27,879.

Referring now to these figures, and particularly to Fig. l. I have shown at a re ervoir for fluid lubricant or oil, which may be suitably disposed at. a convenient poinhthough prefcrablv arranged for disposition and mounting within the hood of the automobile. When F0 disposed it is subect, of course to the heating influence of the automobile motor. so that the oil will be n'uiintained in a fluent state at. all times when the machine is in operation. As shown in Fig. 2 this reservoir has a filling aperturtt normallv closed bv an a 'iertured cap 16. which prevents the within the upper portion oi the reservoir above the surt'ace of the oil 1? as well as above a float 18. This reservoir, as further shown in Fig. 2 may have a gauge glass 19 at one side in order to indicate the height of the tluid within the-reservoir, and is provided in its base with an outlet nipple. 20 having an inner upstamling portion 31. provided with a valve seat 22. The float 18 has a dehollow slotted stem 23 extending downwardly through the nipple 20. and is also provided with .at. the upper end of the stem forming between the same and the stem a valve member 25 adapted in the downward movement of the float to engage the valve seat 22 before the supply of oil is exhausted from the res ervoir.

(ounect'ed to and depcnilling from the nippie Li is a 'l'eed pipe 26 having therein a control valve 27. preferably of the needle type. as indicated in Fig. 2, whereby it may art either as a drip valve or as a cut off. From the feed pipe 26 various branch pipes 28 extend to the several points to be lubricated. tor instance. to thespring shackle bolts 29 of l ig. fl. the steering knuckle bolt fltl ot' l"i. ;.-'l-. and the spring embracing band ill of Fig. 5.

llv ret'erence to Figs. 3, i and 5 in partirular it: will be noted that the branch pipes 26 ((JlllllllllliCfltQill every instance With nip-- pies having therein bushings, the latter of which in accordance with my invention are bored. their teed apertures being sized in ac roi(lai1cC-F- tvith the nccdsoi" the particular bearing in connection with which they are mounted.

Thus in Fig. 3, the branch pipes 28 are shown in connection with hollow i spring shackle bolts 29. the hollows of which have therein absorbent material 32, branch pipes formation of a vacuum an enlargement 2t leis being connected to nip les 33 by virtue of bushin s 34, the latter ored to the desired size an the nipples themselves packed with absorbent material to thus control the feed, the absorbent packing of the nipples being free from any wearing action of the bearing or joint itself. Likewise by reference to Fig. 4 it will be noted that the steering knuckle bolt 30 is hollow with a packing of absorbent material 35 in the hollow thereof and with its nipple 3t; and bushing 37 both packed, the bushing being bored to the desired size. This same construction is fol lowed through all of the movable metal to metal lubricated joints of the chassis and this may include all of the spring shackle bolts, steering knuckle bolts, steering gears, clutch throw-out collar, universal joints, and the like.

- In connection-with the oiling oi the springs 38 as in Fig. 5, one of the branch pipes 28 leads to a nipple 3t) suitably acked to control the feed to the absor 3611i, band 3i cramped around the spring, and it thus obvious that in every instance the points to be lubricated have in connection therewith means capable of assisting gravity by .way of capillary attraction.

It is obvious that in the initial installation, the connection of each of the branch pipes 28 mustbe loosened adjoining that point of lubrication which it supplies, in order to permit the oil to run down into the pipe and it is equally obvious that should one of these connections break the danger of having to repeat this operation would be present it the reservoir were permitted to drain. In accordance with my present construction, however, the reservoir cannot becomeexhausted of its supply of lubricating oil as the float 18 in descending will cause the v alve member 25 to seat in connection with the valve seat 22 and cut oil the outflow of lubricant before the reservoir exv hausts its supply.

In the use of the system having in the feed pipe 26 the valve 27 as per my presentconstruction, it is preferable that this valve be employed as a cut-0E valve and opened up from time to time to permit a supply of oil to run down from the reservoir and fill the several branch pipes. The valve is then closed and under control of the ab .sorbentmaterial packed in the nipples this resume ill vious, however, that another method may' be used and that is to so regulate the valve 27 that it will permit of just sufficient drip from the reservoir into the branch pipesto supply the demands at the various points to be lubricated. In this as well as in the first and preferred methodpthe main consideration is to maintain a proper supply of lubricant and at the same time avoid over supply to the points to be lubricated and the drip or leaking of oil therefrom. 1 claim 2-- 1. A lubricating system for motor vehicles having springs, shackle bolts, steering gears and spindle bolts among other points to. he lubricated, said system including a reservoir, a feed pipe leading from the reservoir and having branches extending to the several points to be lubricated, nipples connecting said branches tothe points to be lubricated and having bored bushings and feed controlpackings of absorbent material, a feed controlling valve in the feed pipe adjacent to the reservoir, and an automatically con trolled valve within the reservoir toprevent exhaustion of its supply of lubricant, for the purpose described.

2. A. lubricating system for motor vehicles having springs, shackle bolts, steering gears.

and spindle bolts, among other points to be lubricated, said system including a reservoir, a teed pipe leading from the reservoir and having branches extending to the several points to be lubricated, connecting members between said branches and said points to be lulnicated having feed control packings of absorbent material, a valve seat formed at the intake end of said feed pipe within the reservoir, and a float in the reservoir having a valve engageable with said seatand arranged to prevent-exhaustion ofthe supply of lubricant, as described.
